ICE-CREAM FREEZER.

Specification of Letters Patent No. 30,256, dated October 2, 1860.

To all whom t may concern.'

Be it known that I, JAMES S. SILVA, of Savannah, in the county of Chatham and State of Georgia, have invented a new and Improved Ice-Cream Freezer; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to t-he accompanying drawing, forming a part of this specification, in which Figure l represents a vertical central section of my invention, the line y, y, Fig. 2 indicating the plane of section. Fig. 2 is a horizontal section of the same taken in the plane indicated by the line x, az, Fig. 1.

Similar letters of reference, in both views, indicate corresponding parts.

This invention consists in the arrangement of a triangular hollow dasher in combination with a scraper of corresponding form, in the interior of the barrel, in such a manner that on turning t-he dasher its three corners scrape off the ice which may adhere to the inside of the barrel, and, on moving the dasher up and down, its sides are scraped off clean by the action of the scraper, and that by this arrangement the formation of ice is considerably accelerated.

To enable those skilled in the art to make and use my invention I will proceed to describe its construction and operation with reference to the drawings.

The barrel A, is made of tinned sheetiron or of any other suitable material; and it is provided with legs a, whereby the same is enabled to stand firmly on the bottom of the tub which surrounds the barrel and which serves to receive the ice in the usual manner.

The barrel A, is furnished with a cover B, which lits nicely over the top edge of the barrel and which turns on the same, the barrel itself being kept stationary by the legs a, A triangular aperture in the cover B, admits of introducing the triangular hollow dasher C, which is also made of tinned sheetiron or of any other good conducting and otherwise suitable material and the aperture in the cover as well as the cross section of the dasher forms an equilateral triangle described into a circle the diameter of which is equal to the inside diameter of the barrel.

When the dasher is inserted into the barrel its three corners touch the sides of the barrel and the latter forms a perfect guide for the dasher.

The dasher is operated by means of a handle D, and in imparting to the dasher a reciprocating rotary motion the ice, which is liable to form on the inside of the barrel, is scraped o" by the action of the corners of the dasher and the sides of the barrel preserve their undiminished quality for conducting the heat.

The hollow dasher C, is packed with ice so that the cream in the barrel is exposed from the outside to the influence of the ice packed around the barrel and from the inside to the infiuence of the ice in the dasher. And the sides of the dasher would be liable to be covered with ice on their outsides after a short time I have provided a scraper E, made of a piece of tinned metal wire and bent so as to fit closely around the dasher. This scraper is guided by an annular recess in the side of the barrel which receives the three corners of said scraper allowing the same to turn freely with the dasher.

By moving the dasher up and down, at certain intervals, the ice which may begin to form on the outside of the dasher, is scraped off and the conductibility of the sides of the dasher is not impaired.

By these means the cream in the barrel is caused to form into ice in a very short time with little labor and with quite a moderate expenditure of ice, and my implement compares favorably with every cream freezer now in the market.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is zl. The arrangement of a triangular dasher C', in combination with the cylindrical barrel A, as described so that in turning the dasher its corners serve to keep the inside of the barrel clear of ice.

2. The arrangement of the scraper E, in combination with the hollow dasher C, constructed and operating substantially as and for the purpose set forth.
